Chrysler Fifth Avenue front inner turn signal bulbs use 2057NA size, front outer turn signal bulbs use 194NA size, and rear turn signal bulbs use 1157 or 2057NA size. The replacement chart covers vehicle production years spanning 1983 to 1989 with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Chrysler Fifth Avenue uses three distinct bulb types across its turn signal positions: the 2057NA, the 194NA, and the 1157, all of which conform to ANSI standards recognized in both the United States and Canada.
The 2057NA is a dual-filament bulb rated at 12V with a high/low wattage of 26.9W and 8W respectively, mounted on a BAY15d bayonet base and fitted with natural amber glass.
The 1157 shares the same BAY15d bayonet base as the 2057NA but operates at lower wattages of 21W and 5W, making the two physically interchangeable in terms of base type while differing in output.
The 194NA is a miniature T10 wedge bulb rated at 12V and 3.78W with natural amber glass, a single-filament design used exclusively in the front outer turn signal position.
The front inner turn signal on the Chrysler Fifth Avenue calls for the 2057NA across the full 1984-1989 model range.
The front outer turn signal position uses the 194NA across the same 1984-1989 range.
The rear turn signal uses the 1157 for model years 1984-1989, while the 1983 model year specifies the 2057NA for that same position.
Because the 2057NA and 1157 share a BAY15d bayonet base, substitution between them is physically possible, but their differing wattage outputs means they are not electrically equivalent replacements.
The natural amber glass on the 2057NA and 194NA produces an amber-colored output without relying on a colored lens, which is a characteristic of the NA designation in ANSI bulb nomenclature.
The 194NA wedge base is mechanically incompatible with the BAY15d bayonet sockets used by the 2057NA and 1157, meaning no cross-position substitution is possible between the outer front position and either of the other two positions.
